Abstract :
The multi-pixel photon counter (MPPC), also known as the silicon photo-multiplier (SiPM), is a novel, solid-state photodetector that contains an array of Geiger-mode photodiodes (called microcells below) to a gain in range of 105 -106 when operating at a low voltage of 40-70 V. The device also has relatively high photon detection efficiency (PDE) and fast timing response. It is also compact and insensitive to magnetic fields. These properties of the MPPC has recently created substantial interest in using the device for PET imaging. In this paper, we evaluate and compare the performance properties of three designs of 1times1 mm2 MPPC offered by Hamamatsu for use in PET. We examine the gains of devices, and also their energy and timing resolutions when coupled to LYSO.
